Electromagnetism & Magnetism Applications Magnetism and moving electrons are closely related to each other. The three phenomena pertaining to electromagnetism are: Moving electric charges produce magnetic fields. Magnetic fields exert forces on moving electric charges. Changing magnetic fields in the presence of electric charges cause electrons to flow In 1820, Danish physicist Hans Oersted noted [...]
Magnetic Core A magnetic core consisting of a plastic or ceramic toroid around which is wound a strip of thin magnetic tape possessing a square hysteresis-loop characteristic. A magnetic core is a piece of magnetic material with a high permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as [...]
What are the Properties of a Neodymium Magnet? The main characteristic of neodymium magnets is how strong they are for their size. The magnetic field of a neodymium magnet occurs when a magnetic field is applied to it and the atomic dipoles align, which is the magnetic hysteresis loop. When the magnetic field is removed, [...]
Frequently Asked Neodymium Magnets Questions What is Rare Earth? Rare earth is an ore primarily mined in China. Rare earth is the source of 17 elements listed on the periodic table as Lanthanides. Two of those elements Neodymium and Samarium are the magnets namesakes that are derived from the rare earth ore. Both Neodymium (Nd) [...]
Rare Earth and Non-Rare Earth Magnets The Differences Between Like in most subjects if you learn the terminology you have at least a consumer level knowledge that will get you to the types, shapes & strength magnets you are looking for. Rare Earth Magnets at MPCO Magnetics Ceramic (non Rare Earth) Magnets at MPCO Magnetics There [...]
Using A Magnet As An Electrical Current Detector An Electric Current Produces A Magnetic Field. You Can Take Advantage Of The Fact To Generate A Simple Apparatus To Check The Electrical Conductivity Of Different Materials, Including Both Solids And Fluids. The Detector Is Composed Of A Coil Of Cable, Using A Magnetic Compass Within It. [...]
Where can I Find Neodymium Magnets Find neodymium magnets at the store If you need a single product or a small batch of neodymium magnets, you don't know how to get these things？ When you need a single magnet and don't want to spend a lot of money to buy the amount of products you [...]
Neodymium Past, Present & Near Future Neodymium is a glistening silvery-yellow metal. It's quite responsive and quickly tarnishes in the atmosphere and the coat of corrosion formed doesn't protect the metal from further oxidation, so it must be kept away from contact with air. It reacts slowly with cold water and quickly with hot. Neodymium [...]
Novel Magnetic Material Discovered in Meteorite Tens of thousands of tons of meteorites fall to Earth every year. Meteorites first came into existence 4.6 billion years ago and since then they have existed in space without changing their form like “fossils” in the solar system. Research on the history of the solar system has been [...]
Automotive Magnets At first glance, it may not look like it, but magnets are increasingly used in a wide variety of areas of the automotive industry. Not only on the production lines, but also in the car itself: in loudspeakers, ABS systems, windscreen wipers or in the door lock, magnets can be used everywhere. Magnets [...]
What Makes a Magnet Stick? The Science Behind Magnets Magnets are a little magical, but mostly they obey the rules of physics. How can you trust the power of your magnets? Learn the science! The fascination with magnets starts early in life, with children performing tiny experiments to see what they can do with the [...]
How Does Temperature Affect Different Magnets? The relationship between magnetic strength and ambient temperature is somewhat complicated. If you are in need of a magnet, however, it is important for you to understand how temperatures affect the strength of different types of magnets before choosing a product. This will allow you to choose the magnet [...]
